Designed with state-of-the-art network processing technology, the SLX 9850 has a non-blocking switching capacity of up to 230 Tbps. An advanced distributed hardware architecture with fine-grained QoS support enables full-duplex, high-speed performance for any mix of IPv4, IPv6, MPLS and BGP-EVPN VXLAN Overlay services. This innovative system architecture offers several distinguishing characteristics:

  • Clos-based distributed non-blocking architecture: Provides the foundation for a robust, scalable data center platform.
  • Midplane-free design: Allows interface modules to communicate directly with switch fabric modules, enabling the chassis to have an efficient front-to-back airflow design and no signal integrity degradation.
  • High-availability implementation: Provides a clear separation between the control plane and data plane at 10 Gigabit Ethernet (GbE) speed to enable operational performance at high loads.
  • Distributed network processing, ultra-deep packet buffers, and advanced QoS capabilities across the system: Streamlines execution of a rich feature set at high data rates, even for bursty or long-lived traffic flows.
  • Complete redundancy: Features a fully redundant architecture with redundant power supply modules, management modules, fan modules, and switch fabric modules to minimize single points of failure.

The SLX 9850 is available in two different models: the SLX 9850-4, a four interface-slot system, and the SLX 9850-8, an eight interface-slot system. Management modules, interface modules, and power supply modules are interchangeable across both the four- and eight-slot models, thereby decreasing inventory and maintenance costs. All modules are hot-pluggable, minimizing system disruption when adding or replacing a module.

Future-Ready Platform

Maximize investment protection with cost-efficient density, scale, and performance to handle the exponential growth in network bandwidth, devices, and services.

SLX 9850 Extensible Architecture

The SLX 9850 architecture is designed to support connectivity needs today and well into the future as bandwidth and application workload requirements grow. Its interface modules optimize port density and capabilities, leveraging the latest Intel x86 CPU and merchant silicon packet processor technology for optimal space, power, and cooling in a highly reliable, carrier-class routing platform. The SLX 9850 delivers:

  • Industry-leading 10/40/100 GbE port density/price per blade

  • Chassis capacity up to 230 Tbps to support massive traffic scale

Modular, Virtualized Operating System

The SLX 9850 runs SLX-OS, a fully virtualized Linux-based operating system that delivers process-level resiliency and fault isolation. SLX-OS supports advanced routing and MPLS features, and is highly programmable with support for REST and NETCONF, enabling full network lifecycle automation with Workflow Composer. In addition, SLX-OS is based on Ubuntu Linux, which provides all the advantages of open source and access to commonly used Linux tools.

SLX-OS runs in a virtualized environment over a KVM hypervisor, with the operating system compartmentalized and abstracted from the underlying hardware. The core operating system functions for the SLX 9850 are hosted in the system VM, which runs on both management modules in a redundant operation. The SLX 9850 interface module software is also virtualized, running in a KVM hypervisor on the local processor of the interface module.

This approach provides clean failure domain isolation for the router operating system while leveraging the x86 ecosystem, thereby removing single vendor lock-in for system tools development and delivery. Additionally, it supports a guest VM, which is an open KVM environment for running third-party and customized monitoring, troubleshooting, and analytics applications.
